JSF CDI @Named + isAnnotationPresent + @CustomSecurityAnnotation
CDI doesn't inject a naked CDI bean as a dependency, but a proxy that redirects to the contextual object of the active scope. This proxy class does not have your annotation. See https://issues.jboss.org/browse/CDI-10 for how to unwrap the proxy....
Passing argument to Resource file in o:validateOrder OmniFaces 2.0
The <o:outputFormat var> is set during render response phase. However, the <o:validateXxx message> is evaluated during validations phase, which is too early. Better use #{of:format1()} function instead. <o:validateOrder id="validacionFechaFacturaMayorAFechaEmisionUltimoComprobante" type="lte" components="fechaFactura fechaEmisionComprobanteUltima" message="#{of:format1(msgs['comun.abm.fecha.factura.menor.ultimo.comprobante'], generacionPadronController.fechaEmisionComprobanteUltima)}"...
Override Omnifaces Validation Message with JSF message-bundle?
validation,jsf,omnifaces,message-bundle
This is currently not supported by OmniFaces validator components. As you can see in the source code of ValidateMultipleFields#showMessage(), it's nowhere obtaining the default message from the message bundle as identified by Application#getMessageBundle(). I reported an issue so that the OmniFaces guys are noticed about it and may implement it...
Implement instead of icon in of
jsf-2,primefaces,omnifaces,megamenu,graphicimage
As far as I understand, you was trying to use something like: <p:menuitem ... icon="#{imageStreamer.getImage(23)}" /> This indeed won't work. It would be evaluated immediately when the renderer obtains it. This is also not how <o:graphicImage> works. It postpones the evaluation to the moment the browser actually needs to request...
OmniFaces UnmappedResourceHandler seems to leak resources when composite components are used
jsf-2,memory-leaks,composite-component,omnifaces,unmappedresourcehandler
UnmappedResourceHandler memory leak on composite components is confirmed and has been solved by this commit for 2.1, this commit for 1.11 and this commit for 1.8.3. All versions are as of today available in Maven....
Enum properties are not retrieved by OmniFaces in Spring / JSF projects
jsf,tomcat,el,jsf-2.2,omnifaces
This is more related to EL than to JSF/Spring/OmniFaces. The Apache EL implementation as used by Tomcat is indeed quite restrictive as to reserved keywords. So is for example #{bean.class.name} (as in, print bean.getClass().getName()) possible in Oracle EL implementation as used by GlassFish, but not in Apache EL implementation as...

Auto Code Completion on Eclipse Kepler for Omnifaces o:importConstants
eclipse,java-ee,jsf-2,enums,omnifaces
Basically, this requires a custom Eclipse plugin which recognizes the <o:importConstants> tag and prepopulates the autocomplete menu. As of now, no such plugin exist and there are as far as I know no plans (at least not from our side) for writing IDE specific plugins for OmniFaces tags/components. I must...

This is a bug in MyFaces. I can't tell which MyFaces version exactly contains the fix, but I can tell that this construct works fine in at least MyFaces 2.1.12. However, upgrading MyFaces in WebSphere might not be a trivial task (technically and bureaucracy). Your best bet is to tell...
Can't get Omnifaces resource handlers to work: Unable to find resource
UnmappedResourceHandler doesn't support resource libraries. It's mentioned in the javadoc and showcase. And the following CSS file reference (note: the library is not supported by the UnmappedResourceHandler! this is a technical limitation, just exclusively use name): <h:outputStylesheet name="css/style.css" /> The technical limitation is that it's otherwise not possible to relatively...
Navigate to previous page with JSF
You need the page id you're navigating from somewhere. At first look, keeping it in Session seems to be a good idea, however, this could remain in coflict if you're navigating in multi-tab (sharing same Http Session through different browser tabs). Having said that, the most proper solution for your...

Error Omnifaces o:validateOrder with Rich Faces Calendar component
The <o:validateXxx> components are sensitive to their location relative to the target input components. This is very useful to prioritize validation depending on component's own converter and validators. When placed before the target input components, then they will validate the raw unsubmitted values, and they will run before any of...
omnifaces starting before openwebbeans 1.5.0?
OmniFaces needs to change the check code as it is non-portable. The CDI Specification does not define that the BeanManager nor any Context needs to be available in a ServletContainerInitializer. This is highly depending on the target environment and integration scenario and thus highly non-portable. This is also a regression...
Disable RestorableViewHandler in Omnifaces
It's not possible to disable it without hacking around in OmniFaces source. As per issue 92 this has been fixed by letting <o:enableRestorableView> setting an application wide attribute once it's been used somewhere, so that the RestorableViewHandler can decide whether to try to restore the view or not. Note that...

Primeface Datatable filtering removed when sorting with o:form includeRequestParams=“true”

Ok so i found out that filteredValue was reseted on each ajax call because of the @RequestScoped. I think i was kind of mixing up things. So i switched all @ManagedBeans to @Named then i created a new @SessionScoped Bean with most of the attributes and i @inject a @RequestScoped...
Facelets error page works during ajax request with FullAjaxExceptionHandler, but does not evaluate EL during synchronous request
jsf,error-handling,web.xml,omnifaces
The <error-page><location> must match the FacesServlet mapping in order to get FacesServlet to run on the error page too during an exception on a synchronous request (which doesn't use ViewHandler#renderView(), but RequestDispatcher#forward()). Alter the mapping accordingly: <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.xhtml</url-pattern> </servlet-mapping> Using /faces/* (and *.faces) is soo JSF 1.0/1.1.

Avoid rendering empty byte array with
jsf,omnifaces,graphicimage,conditional-rendering
You'd really better not call that image streamer method in a rendered attribute. It's invoked multiple times during the JSF lifecycle, hereby inefficiently getting the image bytes from the DB every time. The model also doesn't look right in first place. I suggest to change the model. Make the image...

After trying to run a built war and running it on Wildfly standalone, I managed to narrow the problem to Arquillian, after testing Arquillian+Glassfish embedded and running without problems, I figured the issue was Arquillian+Wildfly, some more googling around and I found similar issues that were related to using Wildfly...
EL expressions in Omnifaces CDN resource handler not resolved in Wildfly 9
It's consequence of a bugfix in Weld implementation of WildFly 9. As per issues CDI-525, WELD-1941 and WFLY-4877, the CDI spec appears to be not consistent with JavaBeans specification as to default managed bean name in case the unqualified classname starts with more than two capitals. CDI spec merely stated...
What does omnifaces JNDI.lookup not have a checked exception for NamingException?
Is there a way of just returning null for non-existant variables instead? It does that for NameNotFoundException. The problem was here not in OmniFaces, but in the environment, which was GlassFish 4.1 in your specific case. It unexpectedly wrapped the NameNotFoundException in another NamingException, hereby causing the underlying NameNotFoundException...

How can I embed an SVG image using JSF/OmniFaces/PrimeFaces?
The <o:graphicImage> sets a default content type of image, but your browser apparently didn't swallow that for SVG images. As per this commit, I've for OmniFaces 2.1 added SVG support for <o:graphicImage dataURI="true"> and I've added a new type attribute which allows you to explicitly specify the image type via...
